The mutation and deletion of the multiple tumor suppressor genes, including p53, Rb, APC and MCC in the same tissue of humanesophageal cancer (EC) and adjacent non-tumor were analysed by PCR amplification and direct sequencing. In 10 cases of EC 6 were found mutations of p53 gene, 5 were found abnormality of Rb gene, 3 were found mutation of APC gene, 3 were found mutation of MCC gene, 8 were found atleration abnormality of tumor suppressor genes Rb, p53, APC and MCC, 6 were found two or more abnormality of the tumor suppressor genes. The results indicated that the alterations in multiple of tumor suppressor genes were related to carcinogenesis of human esophageal cancer.
